improved gas burner which is especially desirable for use in gasheating stoves ments.

Third, to provide an improved gas burner in which the combustion of the gas is very complete.

Fourth, ,to provide an improved gas burner having a multiplicity of tips in which the several tips burn with substantial having radiating eleuniformity.

Further objects, and obj ects relating to dey tails of construction and operation will definitely appear from the detailed description to follow. a

I accomplish the objects of my invention by' the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims. I p A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawings forming a part of this specification, in which:

Figure I is a detail front elevation of a gas heating stove embodying the features of my invention.

Fig. II is a detail horizontal section on a line corresponding to line 2-2 of Fig. I.

Fig. III is a detail vertical section on line corresponding to line 3-3 ofFig. I.

Fig. IV isa detail longitudinal section on line corresponding to line 4-4 of Fig. II.

Fig. V is a detail perspective view of a portion of the burner proper removed from the stove. Fig. VI is a plan view of one of the burner tips.

Fig. VII is a vertical section of one of the,

burner tips on a 77 of Fig. VI.

In the drawing, acters refer to similar line corresponding to line similar reference charparts throughout the embodiment several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the stove structure illustrated is an embodiment of certain features of my improved gas stove illus-' trated and described in my application for Letters Patent filed May 18, 1916, Serial No. 98,337. I have illustrated only such parts of a gas stove as I deemed desirable to show my have put it into practice.

The base 1 is provided with burner openings 2 above .which are the tubular radiating elements 3. The radiating elements 3 are supported in position over the burner openings '2 by means of the lugs 4 and 5, see Fig. II. The fire back 6 is positioned behind the lugs 5. The walls of the casing are of the wall forms no part of thisinV'ention and are a part of my application I do not describe the same in further detail herein.

' The base 1 is provided with a skirt 6' in which the upper portion of the burner is disposed.

My improved burner comprises a plurality of burner tubes 7 formed as an integral casting, the tubes being connected by the vertical centrally disposed web.8. .This

present invention in a practical.

which is the form in which mounted upon this base but as the details web preferably extends from'the top to the 7 bottom of the tubes, cessed at 9 between the tubes.

being preferably re- The tubes and web are also provided with the longitudinal side flanges 10, which are-in the preferred embodiment disposed centrally and extend at each end to provide burner supporting'ears 11. ears 11 are secured to the depending burner supports 12 ofthe base, see Fig. IV. The burnerbody is also provided with projecting manifold supporting ears 13 at each end.

The burner tubes -8 are preferably expanded in their upper portions, the expansion being above the flanges 10. Thev burner tips 14 which .are formed of sheet metal are threaded into the burner tubes. The upper ends of these. burner tips are preferably squared as illustrated and provided with cross bars 15. These tips are formed by inserting the {bars in slits in the ends of the tubes. I

While this particular form of burner tip ,is very. desirable for use in this connection I'do not illustrate or describe thesame with further detail herein as it is made the sl1bject'matter of my applicationtfor Letters Patent filed June 10, 1916, Serial No. 102,905, my present improvements being an adaptation of the invention of that application.

The manifold 16 is provided with upwardly projecting bosses 17 at its ends which rest against the under sides of the manifold supporting ears 13 and are secured thereto by the screws 18, see Fig. IV. The manifold is thus supported in a spaced relation to the lower end of the burner tubes so that there is an unobstructed space permitting free and unobstructed circulation of air to all of the tubes. The manifold is provided with nozzles 19 which are disposed to deliver centrally to the burner tubes. These nozzles may be removed without dismounting the manifold which is advantageous as it per-, mits the cleaning of any nozzle that may happen to become clogged without disturbing any other nozzle.

The manifold is provided with a valve casing 20 which is disposed centrally and transversely of the manifold, the valve casing-being formed integrally with the manifold. In its rear end the valve casing has a flanged coupling member 21 to which the coupling 22 of the supply pipe 23 is secured by means. of the screws 24. The valve 25 for themanifold seats rearwardly and its stem 26 projects outwardly at the front of and centrally below the base. This brings the valve in convenient position for manipulation and does not unbalance or distort the appearance of the structure.

My improved burner is very efficient, the flames being exceedingly hot and do not stream or flash up but the gas burns close to the ends of the tips. The burner formed as illustrated and described serves as an effective radiating means so not become unduly heated notwithstanding the plurality of burners and l-ar e amount of heat given off therefrom. I fin in practice that in gas stoves of this type, that is, employing radiating elements, it is quite difficult to heat the elementsto uniform incandescence and that my improved burner is highly eflicient for that purpose.

The positioning of the tips so that their upper surface is flush with the upper face of the base also has its advantages in securing the best results.

The arrangement of the manifold and burners as I have described secures uniformity in the delivery of the gas and the several burner tips burn with substantially uniform flames which is another feature of distinct advantage and a great improvement over any prior structure which has come to the applicants attention.

y improved burner has the further advantage of being comparatively simple and that it does economical in structure and there are no parts which are likely to be gotten out of adjustment by the user or an unskilled workman.

I have illustrated my improvements in the form in which I have embodied the same in practice. I have not atempted to illustrate certain forms oradaptations thereof as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention, what claim as new and desire to secure by Letters Patent, is: 80
